200 Sickened by "Tuna Scrape" Salmonella Outbreak

The outbreak in multiple states was traced to the ground tuna used in spicy tuna sushi rolls

Tuna scrape, the ground tuna product used in spicy tuna sushi rolls, is suspected to be behind the outbreak of salmonella that has sickened at least 200 people, the CDC reported Thursday.

At least 200 people have now fallen ill from an outbreak of salmonella traced to the "tuna scrape" used in spicy tuna sushi rolls, the Centers for Disease Control and Prevention announced Thursday.

That outbreak actually involves not one but two strains, salmonella Bareilly strain and salmonella Nchanga, the latter of which the CDC said is "extremely rare" in the United States.

The outbreak spans 21 states and Washington, D.C, with the most people affected in New York, New Jersey, Massachusetts, Maryland, Illinois and Wisconsin, according to the CDC.

Of the 200 reported victims, 28 of them had been hospitalized, but nobody had died.
